Patch avoiding-mmap-fragmentation-fix-2.patch oops

Hi

I'm using kernel 2.6.12-rc5-git1
with patches from -mm
avoiding-mmap-fragmentation.patch
avoiding-mmap-fragmentation-tidy.patch
avoiding-mmap-fragmentation-fix.patch
avoiding-mmap-fragmentation-revert-unneeded-64-bit-changes.patch
avoiding-mmap-fragmentation-fix-2.patch

I get a oops when exiting from mplayer playing (dfbmga framebuffer):-

xxxxxxxx.xxxxxxxxxxxxxx.com login: Unable to handle kernel paging request at

(sorry didn't have linewrap on my minicom!)

Without the last patch, avoiding-mmap-fragmentation-fix-2, works fine doing
same stuff with mplayer.

More information/testing can be supplied/performed as required.

Thanks
